Do I have paranormal activity occurring in my house?

Some weird things have been happening lately. My sister was in her room and was getting ready to go somewhere. She picked up her sweater, tried it on, then put it back on her bed. She left her room for a bit and when she went back the sweater was gone. She was confused because she hadn't left the room with the sweater and no one else went into her room. Days later we found it in a pile of socks in my parents closet. Another occurrence is the other day I was eating and I went into the kitchen to grab a knife. I returned back to my food with the knife, and put it under the plate where I couldn't see it. When I grabbed it again, it was a fork. The last thing that happened was I was sitting in the living room, across from my room, watching a movie. I was home alone in my house and would be for the next few hours. I went into my room, grabbed my iphone, and returned. I shut the door to my room all the way and heard the door click. About 10 or 15 minutes later I looked over at my room and the door was halfway opened, and still I was home alone. I don't know if this means something in my house is paranormal, or I'm losing my mind. If someone could help me out that would be great.

Get a priest to bless your house thats what i would do

Maybe your sister is just messing with you if not id say its all in your head you have some what convinced yourself that there's paranormal activity in your house so you are over re acting at the smallest of things ignore it and you will get over it eventually

They are demons taking you away from God.
Accept God into your heart an he will keep you in his arms away from those if you have faith in Jesus Christ. Next time that happens say OUT LOUD God is in my presence and he will kick you out he is the great and powerful. God will always love you!

It appears you are suffering from gullibulitus, a strange disease.
The only cure is to sit on your couch in the middle of the night, forever.

NAH! Thats normal! That stuff happens every day to me! Right?

The first one seems like just an act of misplacement. Happens to me all the time. The second one, I sort of don't believe that. Ghosts aren't magicians. The last one, my door always does that. Perhaps your doorknob is messed up or your house is off level.

Well there's something weird going on in there. Try to call in the Ghost Hunters or let me in your house for 3 days and the spirits will go away. I'll use this device which I call 'Nullfier' it will scare them out so bad that they will not think twice to leave.
